Most common cause is viral. The pain is [blank_start]disproportionate[blank_end] to mucosa appearance. Bacterial causes [blank_start]purulence[blank_end]. 10% of causes are [blank_start]fungal[blank_end] and this is under diagnosed, causes [blank_start]whitish[blank_end] speckling of glottis or supraglottis but can show erythema and oedema without these plaques.
